17.10.2017 · Newton Forward And Backward Interpolation. Interpolation is the technique of estimating the value of a function for any intermediate value of the independent variable, while the process of computing the value of the function outside the given range is called extrapolation. Forward Differences: The differences y1 – y0, y2 – y1, y3 – y2 ...

Gauss forward formula is derived from Newton’s forward formula which is: Newton’s forward interpretation formula: Yp=y0+p.Δy0+ p(p-1)Δ2y0/(1.2) + p(p-1)(p-2)Δ3y0/(1.2.3)+….

1. Forward Difference 2. Backward difference 3. Central Difference The common Newton’s forward formula belongs to the Forward difference category. However , the Gaussian forward formula formulated in the attached code belongs to the central difference method. Gauss forward formula is derived from Newton’s forward formula which is:
